Three years ago, once in Beijing Jingdong grabbed 99 yuan of Ott Blue Star iPad base speaker, as the base speaker for iPhone 4 and iPad 2. Just heard that Haier wireless launched a new QI wireless charging Bluetooth speaker, support QI wireless charging technology, just to replace the Altec Lansing MP450 interface has not taken, but also along the way to experience the latest wireless charging technology. When the new Bluetooth speaker arrives at home, the old Altec Lansing MP450 will be laid off. Outland Bluestar MP450 is also a helpless choice for being laid off. At that time, the price of 99 yuan is almost invincible. But there is no way, the Queen's phone has long been replaced by the iPhone 6S Plus, only 3.5mm of the audio cable to sing songs, with the speaker with the infrared remote control does not support plug-in headphone hole playback pause and play and other convenient operation. And even this 3.5mm headphone jack will disappear next year. So chasing the iPhone to upgrade the speaker interface is not an ideal solution. Theoretically, Bluetooth 4.0 speakers that support the lossless transmission of CSR Apt-X should be able to solve the problem of the replacement of mobile audio cable interfaces in recent years. Although the iPhone does not support Apt-X lossless transmission: (Also talking about this Haier QI Bluetooth speaker male voice prompts feel a bit strange, the sister said that he is still accustomed to Xiaona and Siri as soft female prompts:) Speaker built-in 2600mAh battery (A wealth of burglary that this volume built-in 5000mAh would be better, anyway, is already a chubby pier ^_^), can support everyone to go outdoors, to travel, to Party Happy, no AC power state 10 Hours play After receiving the link range, the speaker will automatically use the male voice prompt sound: "Bluetooth has been connected" will automatically connect, Ah Cai basically can hear with the Queen into the home. How is this speaker sound effect? The subjective sound of human hearing is very clear and the bass strength is not bad, especially the low frequency components. This type of Bluetooth portable speaker is strictly speaking a single speaker, even if the design has two channel speaker spacing is not more than 20cm, natural stereo effects are more difficult to produce color, because the sound field is relatively narrow, the pursuit of ventilation and saliva sound like HIFI The detail resolution feels more general. However, the effects of the midrange and vocal effects of Haier's QI Bluetooth speakers are very clear, and they are suitable for playing some of the atmosphere BGM, listening to favorite webcasts and the like during the daily weekend breaks. Wireless charging The application of this Bluetooth speaker can also be in the bedroom bedside table in addition to the living room. In this way, you do not need to get up before you go to bed to find the USB Cable to charge it. You can automatically charge the wireless phone when you put it on the phone. It will be natural to wake up until dawn. Everyone does not have to worry about the radiation of wireless charging. It is only 1/20 of the radiation of mobile phones that has passed the industry standard test. It is far lower than mobile phone radiation. Wireless charging is actually "near-field microwave oven technology," so a coil of mosquito coils is needed to receive charging energy. Samsung Gasoline S6/S7 body built-in coil, direct support for wireless charging. iPhone 6S Plus also needs to be very elegant with mosquito coils. Of course, the mosquito coil kit is also the Lighting interface form, and ultimately it will be replaced at the end of this year a wireless mosquito repellent set - of course, if the Apple iPhone 7 officially supports wireless charging technology without the need to bring more perfect. In fact, this function of wireless charging does not require Haier Wireless Charging's mobile phone App to intervene. Basically, the wireless charging position of the speaker can automatically start charging. In fact, the phone is on the Haier Qi wireless charging Bluetooth speaker, the location of the automatic charging began, you do not need user intervention, use can be convenient. During charging, the Haier Bluetooth speaker will prompt the charging icon to flash at the respiratory rate. Because iPhone 6S Plus does not support fast charging, the battery capacity of the 2750mAh is so large that the speed of charging the original thunderbolt port is unsatisfactory. Through Haier QI wireless charging Bluetooth speaker, charge about 13% for about 30 minutes. My family is used to charging less than 20% of the electricity. It is expected that the charge will be from 20 to 100%, and the iPhone 6S Plus can be filled for an average of 3 hours. Do you feel the difference between wired/wireless two-generation charging technology? Speaker back interface - AUX mode Of course, most portable Bluetooth speakers also support the AUX input of the 3.5mm headphone jack. Of course, Haier's random audio cable is not enough fever. However, Ah Cai should look at Amway. The speaker audio cable cannot be sloppy. He has always used the Furukawa oxygen-free copper wire + Sennheiser gold-plated plug to reduce line loss and increase sound quality. This entry-level Furukawa fever wire and the manufacturer's original black glue line, the absolute ear can feel the volume attenuation is not the same! If you can't hear it - Congratulations, you gave birth to a pair of fungus. You don't have to burn audio equipment in this life! Speaker back interface - USB mode Haier's speaker also supports Aunt Bee-style functionality - right! U disk storage song USB play function. The aperture of the speaker in USB playback mode is green. This feature can be remotely controlled by the mobile App. Acai believes that this feature is still suitable for Auntie. Young people still use QQ music or shrimp songs to play. to sum up Emphasis: Because of the market chaos and the cheating of bad dealers, most people simply don't understand USB 3.0 and USB 3.1. USB 3.1 Gen1 is USB 3.0. And USB 3.1 Gen2 is the real USB 3.1. The maximum transmission bandwidth of USB 2.0 is 480 Mbps (i.e. 60MB/s), USB 3.0 (i.e. USB 3.1 Gen1) is 5.0 Gbps (500MB/s), and USB 3.1 Gen 2 is 10.0 Gbps (although the nominal interface theoretical rate of USB 3.1 is 10Gbps), but it also retains some bandwidth to support other functions, so it has a good performance. The actual effective bandwidth is about 7.2 Gbps. USB 2.0 is a four-pin interface, and USB 3.0 and USB 3.1 are nine-pin interfaces.

Did not expect the past three years, although the iPad 2 has not yet been eliminated, but has already become a mother's video dedicated tablet, not at our home. One year after the purchase of the base speaker, the standard interface of the iOS device has become the Lighting interface, and the Ott Bluestar iPad base speaker has become a pure 3.5mm headphone speaker. However, the base speaker of the Lighting interface is obviously not happy, because the iPhone will change the USB Type-C interface again next year. 
Bluetooth pairing is also very simple, long press the power button for 3 seconds to enter the pairing mode, and then you can start pairing with the phone connection (iPhone NFC is limited to Apple Pay, can not be used for Bluetooth speaker pairing) 
Acai is satisfied with the Bluetooth playback function of Haier's QI Wireless Bluetooth Speaker, but the wireless charging technology still needs one or two generations of evolution to mature. Tamaic Haier Wireless official flagship store price a few days ago speaker 529, send wireless charging back paste (mobile phone shell). It's worth buying!
USB 3.1 is the latest USB specification, which was initiated by big companies such as Intel. Compared with the existing USB technology, the new USB technology uses a more efficient data encoding system and provides more than twice the effective data throughput (USB IF Association). It is fully downward compatible with existing USB connectors and cables.
USB 3.1 is compatible with existing USB 3.0 software stacks and devices

Intel, which owns Thunderbolt technology, also welcomes the formation of the USB 3.1 standard. USB 3.1 contains most of the features of USB 3.0 [2]. USB 3.1, as the next generation of USB transmission specifications, is commonly referred to as "SuperSpeed+", which will replace USB 3.0 in the future. [3]
